Laser thermal transfer method, or LT2M was performed on PET and glass substrates with Cu, ITO (Indium Tin Oxide), using microwire conductive patterning. PET substrate Cu 1.5 μm was printed with a line width of 75 μm, and also a thickness of Cu 0.6 μm was printed with a line width of 50 μm. On the glass substrate, ITO 0.25 μm thickness was printed with a line width of 30 μm.
